Shell’s Cansolv CO₂ technology

Shell’s Cansolv* CO₂ technology chosen for one of the world’s largest carbon capture projects at a gas-fired cogeneration power station

SC&T supports Calpine’s FEED of a post-combustion CO₂ capture facility based on Shell’s Cansolv CO₂ technology for their Natural Gas Combined Cycle power plant.

Shell Catalysts & Technologies supports Calpine Texas CCUS Holdings, LLC’s (Calpine) front-end engineering design (FEED) of a post-combustion CO2 capture facility based on Shell’s Cansolv CO2 technology for the natural gas combined cycle power plant at Calpine’s Deer Park Energy Center in Deer Park, Texas. The facility will be designed to capture roughly 5 million tonnes net CO2 per year, which equates to 95% of the total CO2 emitted by the natural gas combined cycle power plant each year. The FEED study will be supported by Technip Energies on behalf of Shell Catalysts & Technologies. This is one of the largest CO2 Capture FEED studies awarded worldwide.

The Deer Park Energy Center is a combined cycle cogeneration facility supplying a baseload capacity of over 1,100 megawatts to the Electric Reliability Council of Texas (ERCOT) grid as well as steam to an adjacent facility.

On 6 October 2021, the carbon capture project at Deer Park Energy Center was selected by the U.S. Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management for federal funding as part of the department’s efforts to support transformative and innovative carbon capture and storage technologies. The FEED study is expected to be finalised by early 2023.

Andy Gosse, President, Shell Catalysts & Technologies, commented, “We are very proud to work with Calpine as a partner for this pioneering project. Shell’s CANSOLV CO2 Capture technology has been in operation since 2013, including in a large-scale, commercial, low-pressure application at SaskPower in Canada, where it is designed to capture up to 1 Mt/y of CO2.

This project with Calpine represents a step up in scale and will be a flagship project not only for the companies involved, but also in the world of carbon capture and storage.”

Stan Knez, Chief Technology Officer of Technip Energies, added: “We are pleased to be selected, along with our technology partner Shell Catalysts & Technologies, to work on this leading carbon capture and sequestration project for gas power in the U.S. Decarbonisation is a key part of the energy transition journey and we are glad to bring our technology improvement and integration, engineering and project execution expertise to a pioneer project of such dimension.”

Caleb Stephenson, Calpine’s Executive Vice President of Commercial Operations, said: “We are excited about the opportunity to work with Shell Catalysts & Technologies and Technip Energies to deploy this innovative emission reduction technology.

It is our hope that this is just the beginning of what we can accomplish with the right policies, including the enhanced 45Q tax credit for the power sector that is now being considered in Congress.1 For Calpine, this is a natural part of a comprehensive strategy that includes a variety of major investments in geothermal, energy storage and highly-efficient gas plants to power a cleaner future.

The capture of CO2 reflects Calpine’s ongoing commitment to support a low-carbon economy by delivering reliable, clean energy to customers across North America. At about 5 Mt/y of possible CO2 sequestration from the Deer Park Energy Center, this project promises to deliver carbon reduction equal to taking over one million cars off the road.”

About the CANSOLV CO2 Capture System

Shell’s CANSOLV CO2 Capture System is the only large-scale, post-combustion technology in commercial operation and is based on amine technology.

It uses a regenerable proprietary amine to capture up to 99% of the CO2 from low-pressure, oxidised gas streams. As a low-pressure CO2 capture technology, it is well suited for retrofitting at the tail end of existing plants and greenfield projects. The CO2 is released as a pure stream that can be sold, sequestered or used for enhanced oil recovery. The technology is highly adaptable to a wide variety of industrial applications, gas flow rates and CO2 concentrations from 3.5 to 25% and higher. Licensed units treat gases containing a range of CO2 concentrations at capacities up to 1 Mt/y.
